What Are the Differences Between SIP vs VoIP?

Before we find out the differences between SIP and VoIP, we must first know what they mean. There is some confusion about the facts about VoIP vs SIP; therefore, let’s see if we can break this down so you can understand it better.

Facts About SIP

SIP is an internet protocol designed to maintain, terminate, modify, and initiate communications between VoIP systems. A SIP system works by sending messages and data from one SIP system to another. It eliminates PRI lines contained in traditional landline phone systems and uses the internet to exchange information.

Once SIP is installed, it allows business owners and managers to gain access to call management features such as auto-attendant, call forwarding, voicemail, and more. In the end, SIP enhances the functionality of a VoIP phone system. Since 2010, more than 40 million VoIP phone lines have been added by US companies.

Facts About VoIP

VoIP is also known as Voice Over Internet Protocol and is a cloud-based technology that allows users to send and receive calls over the internet. VoIP service providers that utilize this technology, decode audio to digital information as data packets when sending or receiving phone calls.

The phone on the other end re-encodes the digital information into audio, allowing both the caller and receiver to hear and talk to each other. Unlike a public switched telephone network (PSTN) that uses copper wires, a VoIP phone system uses digital data packets to activate the calls.

VoIP With SIP or VoIP Only: Which One is the Better Option?

Before we begin, one thing you should know is that although SIP extends the functions of a VoIP system, they don’t always integrate. Therefore, you should check the facts about VoIP with your service provider, and they can help you determine if you need VoIP with SIP, or if VoIP only will work for your business based on its demands.

In cases where voice communications only will work for your company, VoIP phones will work just fine. However, if you need multimedia channels, then you should get SIP with your VoIP service providers. Regardless of choice, both phone systems come highly recommended by top leading companies and enterprises.

Let’s take a look at the benefits of VoIP with SIP vs VoIP phone-only:

VoIP Phone-Only

VoIP phone-only systems offer companies a great solution for voice-only capabilities and communications. One of the biggest advantages of VoIP-only phones is the price of their services due to a VoIP phone system only requires a working internet connection. UCaaS Review provides several VoIP service providers with low monthly fees.

VoIP phones also provide flexibility because there isn’t on-site hardware to install and provide flexibility to integrate with current phone systems. Additionally, they can be relocated, making them easy to move and offering special features such as called ID, call forwarding, and call waiting.


If you’re looking for a more advanced VoIP phone system, then you should think about a VoIP with SIP because it’s better suited for modern business communications. VoIP with SIP provides a robust cost saving due to the consolidation of all of your communication platforms and technologies into one system.

SIP trunking with VoIP phones provides redundancy that guarantees your VoIP phone system always sends and receives calls by automatically switching calls to predetermined mobile devices. Furthermore, VoIP with SIP offers business owners scalability and flexibility with new features and the ability to add new phone lines.

VoIP service providers can integrate VoIP with SIP systems with your current infrastructure and business applications already in use. Adding SIP to VoIP phones increases productivity and efficiency and some VoIP with SIP technology can generate a hybrid phone system with existing PRI phone lines.

Can SIP and VoIP Business Phones Replace My Traditional Phone System?

In short, the answer is yes. Many VoIP service providers at UCaaS Review can replace your traditional phone system with new cloud-based phones that operate on the internet as opposed to standard telephone wires. All you need is a reliable internet connection and chose from the selection of available VoIP phones each provider lists.

According to online reports, many companies have made the switch from PSTN systems to more advanced VoIP business phones. One of the biggest reasons is the cost savings on long-distance and international calls as well as the fact that a VoIP phone can be upgraded with new software, whereas the PTSN system isn’t upgradable.
